Title: Double function valve for air conditioning unit - uses linear and rotating movements for flow and mixing functions
Inventor: CLAUSSEN LORENZ DIPL ING
IPC: F16K11/18
Filed: 1978-06-03
Abstract: The valve has actuating element with two degrees of freedom, which ensures two functions enabling use, especially as a changeover valve. The actuating element is connected firmly with a first part of a screw connected pair. Rotation of the screw generates an axial movement for flow rate control. A second screw connection with housing is closed or released. The part of the screw pair released from housing is simultaneously or in succession coupled with the actuating element. This arrangement is used for example in valve where direct axial actuating movement regulates flow rate and rotating movement adjust hot and cold mixture.

Title: Two-stage polymerisation of liq. or solid monomers - initiated by ionised gas plasma
Inventor: OSADA YOSHIHITO
IPC: C08G2/10
Filed: 1978-08-14
Abstract: Polymerisation is carried out by (a) generating anionised gas plasma by an electric field in a confined gas volume, in contact with liquid or solid monomer; (b) propagating the polymerisation through the monomer volume by active centres produced on the interface with the plasma; (c) removing contact with the plasma, whole (d)) polymerisation continues until conversion is at least doubled and the required mol. wt. is achieved. Used esp. for polymerisation of liq. vinyl monomers, e.g. methyl methacrylate and solid cryst, monomers, e.g. 1,3,5-trioxane. Commercial moulding materials with high mol. wt. and purity can be produced, without crosslinking with the low energy consumption compared with usual plasma processes.

Title: Thin wall pipe bending machine - involves reducing wall thickness on one side using special mandrel in drawing device
Inventor: KRAEMER GUENTER
IPC: B21C37/28
Filed: 1979-06-18
Abstract: Pipes can be bent to a relatively small radius by using a special mandrel in conjunction with a two-part die. The mandrel (20) has a tapered head which carries three equally spaced conical rollers (21) mounted on spindles, parallel to the mandrel axis. When used with the two-part die, the wall thickness of the pipe (5) is reduced by an amount varying from zero on one side (24) to a maximum on the opposite side. This variation in thickness causes the pipe to take up the required curvature.
Patent DE-2927978-A1 (DE)
Title: Glow plug with temp. dependent current limiting resistor - has full resistor length at plug operating temp. by forming air gap between body and heating tube
Inventor: BAUER PAUL
IPC: F23Q7/00
Filed: 1979-07-11
Abstract: The construction of a glow plug incorporating both heating element (28) and temperature dependent current limiting resistor (26) inside a tube filled with insulation (22,24) is set out in patent DE2802625. To give the required current regulating effect, it is necessary that the whole length of the resistor (26) is at the glow plug operating temp. In order to achieve the above condition in plug designs requiring a long resistor (26), the hole (18) in the plug body (12) into which the heating tube fits is counterbored. This gives an air gap (36) between the body and the heating tube. The depth of the counterbore is at least as great as the distance to which the resistor element (26) enters the plug body. Loss of heat to the body at the buried end of the resistor is thus reduced and an even temp. equal to that of the glow point results.

Title: Pressure filter with continuously rotating plates - has cylinder divided into zones with air lines between plates
Inventor: KABALA JOZEF DR ING
IPC: B01D33/00
Filed: 1979-09-06
Abstract: A cylindrical vessel having a sealed cover, and provided with constrictions, in which permeable plates suspended from a ring are rotated, forms a continuously acting, pressurised filter. The vessel is divided vertically into three zones and where the zones join each other, sills or baffles of an elastic, flexible material are fitted. Vertical conduits positioned between the plates terminate at the sills, whilst their upper ends are connected to the central control head which regulates the level of the liq. and the supply of compressed air. The arrangement makes it possible to carry out in a single operation, processes such as defecosaturation which previously required two separate processing vessels or a highly complicated arrangement. In the sugar industry, the juice can be filtered without preliminary thickening and the ppte. can be washed and ejected automatically, mixing of the liqs. being prevented by the compressed air conduits.

Title: Aeration system with aeration tube near impeller - directing air jets down impeller cylinder
Inventor: DINNENDAHL MICHAEL ING GRAD
IPC: B01F3/04
Filed: 1980-03-07
Abstract: A vertical counterflow aeration system for activated sludge basins in biological treatment plant uses an impeller near the liquid level, in a vertical impeller tube with vertical laminae. An aeration tube for compressed air is installed in the impeller tube near the impeller and directs jets of air towards the bottom of the basin. Air is thus in contact with the liq. on the down path as well as on the up path. As the air rising velocity must be subtracted from the descending liq. velocity on the down path, a longer mutual contact time will be the result.
